Abstract

A spark plug for an internal combustion engine comprises an elongated center electrode having a center electrode tip at one end and a terminal proximate the other end, an insulator substantially surrounding the center electrode, and a ground shield. The insulator has a substantially cylindrical body with at least a first insulator section and a second insulator section. The first and second insulator sections having first and second diameters respectively and are separated by an insulator shoulder. The ground shield has an elongated base section substantially surrounding the first insulator section, a frustoconical flange protruding from one end of the base section to engage the insulator shoulder, and a ground electrode extending from the other end of the base section to define an axial spark gap with respect to the center electrode tip. The base section and the ground electrode are formed as separate components and secured together to form the ground shield.
